What term describes the passage of some components of the injected embalming solution from an intravascular to an extravascular location?

The term that describes the passage of some components of the injected embalming solution from an intravascular to an extravascular location is diffusion. In embalming, diffusion refers to the process whereby embalming fluid moves from an area of higher concentration within the blood vessels to an area of lower concentration in the surrounding tissues. This movement is essential for the effective distribution of preservatives and antiseptics throughout the body, ensuring proper preservation and minimizing decomposition.

Understanding diffusion is critical in embalming practice, as it underlines the importance of fluid dynamics within the body and aids embalmers in achieving optimal results in tissue preservation.
